[0027] See also Figure 1-7 , the utility model provides a technical solution:

[0028] A portable folding bridge for a riverside highway comprises a bridge deck 1 and bolts, a folding assembly 3 is fixedly connected to the outer side of the bridge deck 1, a connecting plate 2 is rotatably connected to the outer side of the bridge deck 1 via the folding assembly 3, adjacent connecting plates 2 are rotatably connected via the folding assembly 3, through holes 4 of equal apertures are provided on the inner sides of the bridge deck 1 and the connecting plates 2, a connecting shaft 5 is provided on the inner side of the through hole 4, a handrail 6 is sleeved on the outer side of the connecting shaft 5, a pulley 7 is installed at one end of the handrail 6, and a connecting ring 8 for connecting a rope is fixedly connected to one side of the bridge deck 1.

[0029] The folding assembly 3 is composed of a connecting convex plate 301, a connecting rod 302, a connecting concave plate 303 and a sleeve 304. The connecting convex plate 301 is fixedly connected to the connecting rod 302, the connecting concave plate 303 is fixedly connected to the sleeve 304, and part of the connecting rod 302 is arranged on the inner side of the sleeve 304 and is rotatably connected to the sleeve 304. This arrangement allows the bridge plate 1 to be folded with the connecting plate 2, and the connecting plate 2 to be folded with the adjacent connecting plate 2 through the folding assembly 3; the railing 6 is composed of a connecting block 601, a U-shaped card slot 602, a screw hole 603 and a rod body 604, and the adjacent rod bodies 604 are connected to the U-shaped card slot through the connecting block 601. The groove 602 is hinged, and the connecting shaft rod 5 passes through the rod body 604 through the screw hole 603. There are several rod bodies 604, and this arrangement allows the railing 6 to be folded and unfolded; there are two bridge decks 1, and there are several connecting plates 2. This arrangement allows the connecting plates 2 and the bridge deck 1 to be positioned, so that pedestrians can cross the river through the connecting plates 2 and the bridge deck 1; there are several pulleys 7, and the pulleys 7 are evenly arranged. This arrangement allows the entire process to be carried out on the water surface. The pulley 7 can contact the ground during the extension of the device, thereby reducing friction and providing a certain restraint force.

[0030] Working process: The portable folding bridge along the river is transported to the use site through the vehicle-mounted device, and then one side of the portable folding bridge along the river is fixed on one side of the river, and the vehicle-mounted device is connected to the connecting ring 8 on the unfixed side of the folding bridge through a rope, and the vehicle-mounted device is driven from the water to the other side of the river. In this process, the bridge deck is unfolded. In the initial state, the bridge plate 1 and the connecting plate 2 are folded together at a certain angle through the folding assembly 3, and the connecting rod 302 fixedly connected to the connecting convex plate 301 and the sleeve 304 fixedly connected to the connecting concave plate 303 are relatively rotated, so that The bridge plate 1 and the connecting plate 2, and the connecting plate 2 and the adjacent connecting plate 2 can be folded. As the vehicle-mounted device is pulled, the bridge plate 1 and the connecting plate 2 respectively drive the connecting shaft rod 5 to move. The connecting shaft rod 5 is respectively arranged on the inner side of the bridge plate 1 and the connecting plate 2 through the through hole 4. The connecting shaft rod 5 passes through the railing 6 through the screw hole 603, and the connecting shaft rod 5 is connected to the rod body 604 by bolts. The connecting shaft rod 5 drives the railing 6 to move. While limiting the expansion between the bridge plate 1 and the connecting plate 2 and between the connecting plate 2 and the adjacent connecting plate 2, it also prevents the bridge plate 1 and the connecting plate 2 from being expanded to the greatest extent. The folding rotation between the plates 2 and between the connecting plate 2 and the adjacent connecting plate 2 is too large, thereby avoiding folding damage caused by excessive folding rotation angle. The adjacent rod bodies 604 are hingedly connected to the adjacent U-shaped slots 602 through the connecting blocks 601, so that the railing 6 can be folded and unfolded, and the entire device is slowly unfolded. The whole process is carried out on the water surface. The pulley 7 installed at the lower end of the railing 6 can contact the ground during the extension of the device, thereby reducing friction and providing a certain restraint force. After the unfolding is completed, the connecting device between the vehicle-mounted device and the bridge plate 1 is removed. For the convenience of walking, some existing foldable stairs can be installed on both sides of the bridge plate 1. The folding bridge can be applied to a variety of different geological environments and different disasters due to its special mechanical structure. This folding bridge is also applicable to rural areas lacking infrastructure, which can greatly shorten the time of crossing the water and gain precious time for disaster relief personnel. At the same time, it is also a construction bridge, which can save the distance of material transportation and greatly reduce construction costs. When using a portable folding bridge along the river road, a certain foundation must be built on the riverbed with simple materials to support the bridge, increase the stability of the bridge, and avoid some safety hazards such as side collapse.
